Minor head trauma and isolated unilateral internuclear ophthalmoplegia.

Internuclear ophthalmoplegia is a syndrome that develops due to a lesion of the medial longitudinal fasciculus. This lesion is mostly caused by multiple sclerosis (usually bilaterally), and only rarely by head injury. A case is presented of unilateral internuclear ophthalmoplegia as an isolated sequel of minor head trauma, which eventually resolved. A 40-year-old woman with isolated internuclear ophthalmoplegia secondary to closed head trauma with anatomical lesions of the mesencephalon in the region of medial longitudinal fasciculus is described. A minor contusion was detected by magnetic resonance imaging. Diplopia resolved in 5 months. In conclusion, internuclear ophthalmoplegia should be considered in the differential diagnosis in patients with recent head injuries showing adduction impairment. The connection between the clinical picture and anatomical lesions is visualized by magnetic resonance imaging.

Leber's hereditary optic neuroretinopathy (LHON) associated with mitochondrial DNA point mutation G11778A in two Croatian families.

Leber's hereditary optic neuroretinopathy (LHON) is manifested as a bilateral acute or subacute loss of central vision due to optic atrophy. It is linked to point mutations of mitochondrial DNA, which is inherited maternally. The most common mitochondrial DNA point mutations associated with LHON are G3460A, G11778A and T14484C. These mutations are linked with the defects of subunits of the complex I (NADH-dehydrogenase-ubiquinone reductase) in mitochondria. The G11778A mitochondrial DNA point mutation is manifested by a severe visual impairment. In this paper two Croatian families with the LHON G11778A mutation are presented. Three LHON patients from two families were younger males which had the visual acuity of 0.1 or below, the ophthalmoscopy revealed telangiectatic microangiopathy and papilloedema, while Goldmann kinetic perimetry showed a central scotoma. The mothers and female relatives were LHON mutants without symptoms, whereas their sons suffered from a severe visual impairment. Molecular diagnosis helps to explain the cause of LHON disease.

[Combined therapy in glaucoma treatment: travoprost 0.004% and brinzolamid].

AIM: To evaluate the efficacy of travoprost 0.004% and brinzolamide 1% combined therapy in patients unsuccessfully treated with a combination of timolol 0.5% and brinzolamide 1%. PATIENTS AND METHODS: The study was conducted in 30 adult patient with primary open angle glaucoma (14 men and 16 women, mean age 68.5 years) who required change in therapy. Intraocular pressure was measured at entry, and on day 15, 45 and 90 thereafter. RESULTS: The initial mean intraocular pressure was 21.62 mm Hg. Therapy modification (travoprost 0.004% instead of timolol 0.5%), resulted in intraocular pressure reduction by 5.67 mm Hg on day 15, and by 6.37 mm Hg on days 45 and 90. CONCLUSION: The study showed travoprost 0.004% combined with brinzolamide 1% to provide a statistically significant reduction (p < 0.001) in intraocular pressure in patients who could not been successfully treated with timolol 0.5% and brinzolamide 1%.

[Clinical approach to normal intraocular pressure glaucoma].

Normal intraocular pressure (IOP) glaucoma is a clinical condition characterized by pathologic optic nerve excavation and visual field impairment, defined as optic neuropathy with certain features of a disease known as glaucoma. Glaucomatous optic nerve lesion is characterized by optic disk excavation or depression, however, this feature may greatly vary. The level of IOP is considered only one of the multiple risk factors involved in the disease development. In normal IOP glaucoma, papillary lesions and visual field impairments may differ from those occurring in primary open-angle glaucoma. In modern ophthalmology, the terminology has been modified, so the term low IOP glaucoma has been replaced by the term normal IOP glaucoma. It is now believed that various factors play a role in the development of glaucomatous optic neuropathy in normal IOP glaucoma and show variable interference depending on IOP level. Additional studies are needed to define these interactions and their impact on the mechanism of glaucomatous excavation. This will hopefully pave the way to new therapeutic approaches and help in clinical decisions concerning the prognosis and treatment of individual patients.

The appearance of pars planitis in multiple sclerosis.

The aim of the study was to investigate the clinical association of multiple sclerosis and pars planitis (or intermediate uveitis), as well as to determine the incidence of pars planitis in multiple sclerosis patients. During the period of one year authors examined 42 patients with multiple sclerosis divided into two groups. First group consisted of 23 patients with history of optic neuritis and the second group consisted of 19 patients who have never had optic neuritis. The mean age of patients in the first group was 31.7 +/- 5.1 years and in the second group 29.1 +/- 8.1 years. Pars planitis was found in 12 patients with multiple sclerosis. Age, sex and degree of neurological disability had no influence on the appearance of pars planitis. Although optic neuritis is considered to be the most common ocular manifestation of multiple sclerosis, the significant number of patients with multiple sclerosis has pars planitis.

Epidemiology of monosymptomatic optic neuritis in Rijeka County, Croatia: meteorological aspects.

In order to analyze the meteorological factors possibly influencing the monosymptomatic optic neuritis in Rijeka County, northwestern part of Croatia, retrospective analysis of all cases diagnosed in Rijeka County in period from 1977 to 2001, was done. Meteorological data on monthly and yearly temperature, humidity, insolation in Rijeka County were collected from Croatian Meteorological and Hydrological Service. In the observed period there were 173 cases of monosymptomatic optic neuritis, female/male ratio was 1.66, and overall incidence was 2.18/100,000 inhabitants. There was no correlation of incidence with average yearly and monthly temperature, humidity, insolation, or month of birth. This is the first study on meteorological factors and optic neuritis in Croatia.

Doppler-echocardiographic characteristics of left ventricular function in patients with pseudoexfoliation glaucoma: a preliminary report.

Glaucoma is associated with an increased incidence of cardiovascular disease and risk factors. The aim of the study was to assess the left ventricular (LV) function in patients with pseudoexfoliation (PEX) glaucoma using doppler-echocardiographic examinations. Two-dimensional and pulsed Doppler echocardiography of transmitral flow was performed in 21 patients with (PEX) glaucoma and 24 controls. LV systolic contraction and ejection were assessed using the LV ejection fraction (EF) and fractional shortening (FS). LV diastolic filling assessed parameters were: early, fast diastolic filling (E wave), late diastolic filling (A wave), ratio E/A, velocity time integral E wave (VTIE) and A wave (VTIA), their ratio (VTIE /VTIA), pressure at the end of filling (LVEDP) and a pulmonary capillary wedge pressure (PCWP). A significant difference was found concerning LV filling flow parameters in E, E/A, VTIA and ratio VTIA/ VTIE. No significant difference was found in EF, FS, A, VTIE, LVEDP and PCWP tested parameters. Our study indicates the possibility of slightly impaired diastolic function of LV in patients with PEX glaucoma assessed by Doppler-echocardiographic examinations.

Eye disorders in neurofibromatosis (NF1).

Neurofibromatosis type 1 (NF 1) is an autosomal dominant disorder with high index of spontaneous mutations and extremely varied and impredictible clinical manifestations. The aim of this work was to give an account of eye disorders in NF1. 132 patients of age 0-16 years with NF1 were followed up for 15 years. They were checked repeatedly for ophthalmologic disorders. Frequent eye disorders were: Lisch nodules (Iris hamartomas, IH) 78%, hyperthelorism 19.7%, bulbomotoric disorders 15.9%, disorders of the optic disc 16.7% and optic gliomas (18.9%). The highest incidence of eye disorders by NF1 patients showed Lisch nodules (IH). Its ease of clinical recognition and if present with other diagnostic signs (for instance café au lait patches) could be deemed as reliable diagnostic criterion of NF1 in childhood.

Inapparent visual field defects in multiple sclerosis patients.

To assess inapparent visual field defects in patients with multiple sclerosis free from optic neuritis. During 5 years period 120 patients with multiple sclerosis were examined at the University Department of Ophthalmology, Zagreb University Hospital Center. They were divided into three groups with 40 patients each: patients with acute unilateral optic neuritis, referred to ophthalmologist and treated with pulsed steroid therapy; patients with subjective feeling of blurred vision, normal visual acuity and no signs of acute optic neuritis; and patients free from subjective signs of visual impairment. Study patients underwent standard ophthalmologic examination and visual field testing in photopia by use of quantitative kinetic Goldmann perimetry. The initial and control examination by visual field testing were performed at least 6 months apart. Study results showed 65% of multiple sclerosis patients to have visual field defects without subjective signs of impaired vision. The most common defects were mild to moderate visual field narrowing with blind spot enlargement and depression from above. The following results were recorded: acute optic neuritis group: normal in 13/40 (32.5%) for the affected eyes and 27/40 (67.5%) for fellow eyes; mild visual field narrowing in 4/40 (10%) for the affected eyes and 10/40 (25%) for fellow eyes; moderate visual field narrowing with blind spot enlargement in 14/40 (35%) for the affected eyes and 1/40 (2.5%) for fellow eyes; and paracentral and arcuate scotomata in 9/40 (22.5%) for the affected eyes and 2/40 (5%) for fellow eyes; subjective symptom group: normal in 8/40 (20%) for the affected eyes and 11/40 (27.5%) for fellow eyes; mild visual field narrowing in 11/40 (27.5%) for the affected eyes and 16/40 (40%) for fellow eyes; moderate visual field narrowing with blind spot enlargement in 18/40 (45%) for the affected eyes and 10/40 (25%); andparacentral and arcuate scotomata in 3/40 (7.5%) for both affected and fellow eyes; and subjective symptom-free group: normal in 24/80 (30%), mild visual field narrowing in 22/80 (27.5%) moderate visual field narrowing with blind spot enlargement in 24/80 (30%); and paracentral and arcuate scotomata in 10/80 (12.5%). The presence of subclinical form of optic nerve involvement could be demonstrated in a very early stage of multiple sclerosis by the introduction of visual field testing in the standard examination protocol.

Target intraocular pressure in the management of glaucoma.

Achievement of target intraocular pressure is the goal of every efficient antiglaucoma therapy. Target intraocular pressure is the level of intraocular pressure which is associated with minimal likelihood of visual field or optic nerve lesion, or an existing lesion progression due to elevated intraocular pressure. Results of large clinical studies which have offered some new concepts on target intraocular pressure in the management of glaucoma are reviewed. An association between the curve of intraocular pressure decrease and glaucoma progression was demonstrated in these studies. Generally, a lower value of target intraocular pressure implies better protection from the loss of vision and visual field impairment in glaucoma patients. In advanced glaucoma, the greatest possible reduction from the initial intraocular pressure should be attempted. A 20% reduction from the initial intraocular pressure or decrease to < 18 mmHg in advanced glaucoma has been recognized as a favorable strategy to reach target intraocular pressure. In normal tension glaucoma, a lower value of target intraocular pressure is associated with a slower disease progression. In patients with initial glaucoma, 25% reduction from the initial intraocular pressure will slow down the disease progression by 45%. The value of target intraocular pressure depends on the pretreatment level of intraocular pressure, optic nerve condition, glaucoma disease state, rate of glaucoma progression, patient's age, and other risk factors for the development of glaucoma.

Multiple sclerosis and neuro-ophthalmologic manifestations.

The authors report clinical features of ocular manifestations in patients with multiple sclerosis (MS), those that affect the visual sensory system and those that affect the ocular motor system. Disturbances of visual sensory function may precede, manifest coincidentally or follow the neurologic manifestations. Visual disturbances are common in MS and often a result of acute demyelinating optic neuropathy. Careful examination of MS patients, who have never suffered optic neuritis, may also reveal asymptomatic visual loss. Asymptomatic visual loss seems to be a universal feature of MS. Patients with multiple sclerosis may develop disorders of fixation, ocular motility and ocular alignment. Disorders of ocular motor system are frequently the initial sign of multiple sclerosis and occur as its presenting sign weeks, month, or years before other neurologic symptoms and signs develop.

The incidence of optic neuritis in Split-Dalmatia county, Croatia.

The aim of the study was to determine the incidence of monosymptomatic optic neuritis (MON) in residents of Split-Dalmatia County, Croatia. The 127 cases (83 female, aged 26.2+/-9.9 and 44 male aged 26.9+/-11.2) with MON presented between January 1985 and December 2001 were analyzed from hospital data. The annual incidence was 1.6 per 100,000 (95% CI, 0-3). The incidence among females was 2.2 (95% CI, 0-4.6) cases / 100,000 per year and 1.1 (95% CI, 0-3) among males. The difference in incidence rates for women vs. men was not significant (chi2=0.41; p=0.52), although it is more likely that a true difference exists. The peak incidence in both sexes observed in the group 20-29 years of age was 4.2 (95% CI, 0-10). The highest incidence of MON was found in spring (46 cases). In summary, the incidence of MON in Split-Dalmatia County during the 17 years period is relatively low.

Bilateral amaurosis caused by Salmonella enteritidis infection.

The aim of this paper was to show the potential of Salmonella enteritidis infection to eventually result in visual impairment. A case of salmonellosis in a 6-year-old boy, caused by intake of a cake made from eggs infected with Salmonella enteritidis, is presented. Prolonged duration of the disease was followed by complete remission of neurologic complications and persistent amaurosis with bilateral optic nerve atrophy. A severe form of Salmonella enterocolitis with neurologic involvement can lead to optic nerve lesion with consequential loss of vision.

[Lid retraction etiology].

The upper lid position is abnormal if it exposes a white band of sclera between the lid margin and the upper corneal limbus while the retracted lower lid lies below the inferior corneal margin and is tethered to the orbital margin. Lid retraction is a sign of many congenital and acquired diseases and is characterised by multifactorial etiology. The aim of this study was to discuss the etiology of lid retraction divided into four categories: neurogenic, myogenic, mechanical and miscellaneous, what suggests a successful differential diagnostic and therapeutic approach.

A contribution to the surgery of the trachomatous entropion and trichiasis.

Although the WHO document WHO/PBL/93.29 recommends the bilamellar tarsal rotation operation for trachomatous entropion, we will describe another operation that has proved to be very reliable. It is a combined method, consisting of the modified tarsal wedge resection and the eversion splinting-grey line incision. A possible additional correction of the grey line incision on the first postoperative day improves the results. A total of 708 eyes with moderate trachomatous entropion and major trichiasis underwent this surgery, but only 508 of these were followed up during a 6-month period. The rate of failed operations, which consisted of incomplete closure of the lids or more than two inverted lashes remaining, was 6.9%.
