Proptosis: etiology and demographic patterns.

OBJECTIVE: To determine the demographic pattern of patients presenting with proptosis and its etiology. DESIGN: A cross-sectional descriptive study. PLACE AND DURATION OF STUDY: Khyber Institute of Ophthalmic Medical Sciences (KIOMS), Hayatabad Medical Complex, Peshawar from July 2001- December 2002. PATIENTS AND METHODS: Sixty cases of proptosis presenting at KIOMS were included. Thirtysix patients were male while 24 were female. They were divided into two age groups; 0-15 years (paediatric group) and above 15 years (adult group). An elaborate work up plan was formulated for all patients, which included detailed history, clinical examination (ocular, orbital and systemic), radiological and histopathological investigations. RESULTS: Neoplasms (33%) were the most common causes of proptosis in all the patients followed by orbital inflammations (23%), orbital infections (20%), structural abnormalities (12%), vascular abnormalities (7%) and trauma (5%). CONCLUSION: Neoplasms were the most common cause of proptosis in both paediatric and adult group. Proptosis was the cardinal feature and visual deterioration was present in more than half of the patients. Timely referral, early diagnosis and appropriate management can result in reduction of visual morbidity.

Ocular emergencies.

OBJECTIVE: To describe clinical data about ocular emergencies (OE) and their management. DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: This study was conducted from 1st January, 2000 to 31st December, 2002 at the Department of Ophthalmology, Khyber institute of Ophthalmic Medical Sciences, Lady Reading Hospital, Peshawar. MATERIAL AND METHODS: A comprehensive analysis of the computer record available for admitted ocular emergencies was undertaken in terms of gender, age, etiology, procedure performed and hospital stay. RESULTS: Ocular emergencies (1961) were 18.49% of total admissions. Male to female ratio was 2:1. Non-traumatic ocular emergencies were 1058 (53.95%) with male to female ratio of 1.47:1. In the non-traumatic ocular emergencies, majority (67.2%) were 40 years or above. Traumatic ocular emergencies were 925 (47.16%) with male to female ratio of 2.77:1. Majority (83.78%) of traumatic ocular emergencies were below 40 years and 562 (60.75%) below 20 years of age. Only 150 (16.21%) cases were 40 years and above. Corneal ulcers (44.51%) and glaucoma (24.38%) were the most common non-traumatic ocular emergencies, whereas, open globe injuries (73.4%) were leading the traumatic ocular emergencies. Total surgical procedures performed were 1382 (13.7% of total major ophthalmic surgery). Average stay in hospital was 5.5 days. CONCLUSION: Ocular emergencies predominantly affected the males in this series. Trauma related OE are almost as common as non-traumatic. Majority of OE need surgical intervention and the average hospital stay is longer than routine admissions.

Conventional retinal reattachment surgery.

OBJECTIVE: To evaluate the surgical outcome in rhegmatogenous retinal detachment (RRD) cases operated by conventional retinal reattachment techniques. DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: This study was conducted at Eye Unit, Hayatabad Medical Complex (HMC), KIOMS, Peshawar, from July, 2002 to December, 2002. MATERIALS AND METHODS: A retrospective analysis of ophthalmic record of rhegmatogenous retinal detachment operated by conventional retinal reattachment surgery was done. Anatomic outcome was evaluated in relation to duration of presentation and pre-operative proliferative vitreoretinopathy (PVR). Postoperative visual acuity (VA) was compared to pre-operative VA. Complications and causes of failure of anatomic success were also analyzed. RESULTS: A total of 40 cases were studied. Male to female ratio was approx 2:1. Retinal breaks were localized in 70% cases, 37.5 % cases had single break while 32.5 % cases had more than one retinal breaks. Forty two percent had total retinal detachment while 57.5 % had less than total retinal detachment. Five percent had attached macula at presentation. Immediate postoperative retinal reattachment was attained in 80% cases but ultimate anatomic success after at least 6 months of follow up was 72.5%. Patients who presented earlier (upto 1 year) had 75% anatomic success while those who presented later than 1 year had 50% success rate. Postoperative visual improvement was noted in 80 % cases with flat macula, 65% had VA 6/60 or better after surgery. Most common cause of failure of anatomical reattachment was PVR (63.63% of failed conventional surgery). Most common postoperative complication was raised intraocular pressure ( > 21 mmHg) in 25 cases. CONCLUSION: There is more chance of retinal reattachment and visual restoration in cases that present earlier. PVR is the main cause of failure of conventional retinal reattachment surgery. Postoperative visual improvement is directly related to surgical reattachment of the macula.

Corneal complications of vernal catarrh.

OBJECTIVE: To identify the magnitude and types of corneal complications of vernal catarrh and the extent of visual impairment caused by them. DESIGN: A cross-sectional study. PLACE AND DURATION OF STUDY: Khyber Institute of Ophthalmic Medical Sciences (KIOMS), Hayatabad Medical Complex (HMC), Peshawar, from March, 1999 to May, 2000. SUBJECTS AND METHODS: All cases of vernal catarrh who agreed to an informed consent were included in the study. Patients who were difficult to be examined by a slit lamp were excluded from the study. The diagnosis was made mainly on the basis of history and clinical examination. Slit lamp examination was done in every case together with fluorescein staining of cornea. The variables were recorded and statistically analyzed. RESULTS: Superficial punctate keratitis (45%) was the most common corneal complication. Visual impairment was more pronounced in cases with shield ulcers (14%) and corneal plaques (8%). A strong association with keratoconus (15%) was also noted. Corneal opacification (9%), hydrops (6%) and pseudogerentoxon (3%) were also found. CONCLUSION: Corneal complications in VKC are common, potentially serious and may cause marked visual impairment.
