Visual function following congenital cataract surgery.

To evaluate the results of congenital cataract extraction and postoperative visual function, we retrospectively reviewed the records of 95 patients who underwent pars plana (plicata) lensectomy or aspiration surgery. Forty-nine percent of the patients with bilateral aphakia and 25% with bilateral pseudophakia had a Landolt visual acuity of 0.5 or above at the final visit. The figures were 31% and 66% for patients with unilateral aphakia and pseudophakia, respectively. Eight patients (16.3%) with bilateral and 2 patients (5.8%) with unilateral cataract for whom contact lenses were prescribed after surgery attained fine stereopsis. Five of 8 patients (62.5%) with unilateral cataract who had intraocular lens implantation ended up with gross or fine stereopsis. We stress that very early surgery and optical correction in the sensitive period of binocular visual development should be instituted, especially in the presence of dense opacities. A good postoperative visual outcome can be achieved in patients undergoing late surgery if the opacities are light or partial in nature. We also reemphasize the importance of aggressive and diligent visual rehabilitation and occlusion therapy against amblyopia.

Ocular surface disease in atopic dermatitis.

PURPOSE: To describe the ocular surface disorders of 362 patients with severe active atopic dermatitis (AD) treated in the Ophthalmology Department of Kobe University Hospital and Kobe Rosai Hospital Eye Clinics during the period 1994-1996. METHODS: Routine ophthalmic examinations as well as tear film break-up time (BUT) and Schirmer tests were carried out. RESULTS: Lid eczema (65.7%), atopic keratoconjunctivitis, and superficial punctate keratopathy (67.5%) were the dominant ocular diseases in these patients. Tear function tests showed a BUT value of less than 10 seconds in 62.4% of the eyes and a Schirmer test value of less than 5 mm in 56.2% of the eyes. CONCLUSIONS: A careful examination of the ocular surface is essential in treating AD patients. We also suggest that the ocular surface disorders in AD may be due to allergic reactions and disorders in tear film quantity or quality.

Long-term visual outcome in proliferative diabetic retinopathy patients after panretinal photocoagulation.

BACKGROUND: There is the need for a long-term study on the visual outcome of panretinal photocoagulation (PRP) for proliferative diabetic retinopathy (PDR) patients. CASES: We retrospectively reviewed the clinical course and visual results in 66 eyes of 59 patients with PDR who were followed-up for at least 10 years after argon or krypton laser PRP. OBSERVATIONS: Thirty-nine eyes had stage B-II, whereas 8 eyes had stage B-III retinopathy. Stage B-IV and B-V retinopathy were seen in 15 and 4 eyes, respectively. Although active stages of diabetic retinopathy were encountered after 5 years, complete regression could be successfully attained after 10 years. Long-term visual prospects were promising for eyes with stage B-II DR; 28.2% still enjoyed 20/40 or better visual acuity by 5 years. Most cases had maintained the same visual acuity at 10 years. Eyes with stage B-III DR did not attain 20/40 vision by 10 years. Panretinal photocoagulation in cases with neovascularization of the optic nerve head was seen to be beneficial but limited, suggesting that such cases might benefit from maximal initial and supplemental PRP followed by vitrectomy and intraoperative endophotocoagulation when necessary. Although 20% of the eyes with stage B-IV and 25% of the eyes with stage B-V DR had 20/40 or better visual acuity, analyses of the visual change revealed that about half the eyes with stage B-IV and all eyes with stage B-V DR experienced a visual loss of two lines or more. CONCLUSIONS: Progression of lens opacities, chronic macular edema, vitreous hemorrhage, macular traction, and neovascular glaucoma were the main causes of visual loss in this series. Panretinal photocoagulation for PDR provides good anatomical and visual outcome for 10 years or longer.

Effect of retinopathy of prematurity on resolution acuity development in 1- to 3-year-old children.

PURPOSE: To assess the pattern of visual development in children aged 1-3 years with stage 1-3 retinopathy of prematurity (ROP). METHODS: One hundred forty-four infants weighing <1500 g were divided into three groups according to ROP stage. Randomly chosen preterm infants were the controls. Ophthalmic examinations started 4-7 weeks after birth and were performed until the retina was fully vascularized or until any ROP that had developed resolved. Preferential looking acuity measurements were carried out at 12, 18, 24, and 36 months of age. RESULTS: Infants with stage 1-2 or no ROP showed evidence of improving acuity development after 12 months. Infants with stage 3 ROP had significantly lower acuity scores compared to infants with stage 1-2 or no ROP at the 18- and 24-month follow-up examinations (P<.001). At 36 months, the visual acuity of infants with stage 3 ROP showed evidence of improving development but still lagged behind infants with stage 1-2 or no ROP. CONCLUSION: Although mild ROP does not seem to have a considerable effect on the development of resolution acuity until age 3, severe forms of ROP may be associated with impaired visual development, which strongly suggests the necessity of periodic monitoring of early visual acuity in infants with ROP.
