Intravitreal bevacizumab in central serous chorioretinopathy

To evaluate the effect of intravitreal bevacizumab injection in patients with central serous chorioretinopathy [CSCR]. Quasi-experimental study. Layton Rehmatullah Benevolent Trust Eye and Cancer Hospital, Lahore, from July 2010 to April 2011. There were 43 eyes of 32 adult patients with CSCR. Patients with choroidal neovascularization, prior treatment for CSCR, history of thromboembolism, intraocular pressure more than 21 mmHg, history of retinal detachment, intraocular inflammation, and allergy to fluorescence were excluded from study. All patients had intravitreal injection of off label bevacizumab. At baseline and follow-up visits, patients had best corrected visual acuity [BCVA] and central macular thickness [CMT] measurement with optical coherence tomography. They were followed-up for 6 months. Outcome measures included BCVA and CMT. Wilcoxon Signed Ranks test was used for evaluation of BCVA and CMT. There were 26 [81.3%] males and 6 [18.7%] females with 21 [65.5%] cases of unilateral and 11 [34.5%] cases of bilateral involvement. Mean age was 39.09 +/- 8.49 years. Nineteen [59.4%] eyes showed less than 6 months involvement and 13 [40.6%] eyes showed more than 6 months involvement. Mean number of injections required was 2.37 +/- 1.24 in acute cases and 3.05 +/- 1.39 in chronic cases. Overall mean of required injections was 2.67 +/- 1.34. Median visual acuity at baseline was 0.25 and at 6 months was 0.7 [p < 0.001]. Median CMT at baseline was 557 micro and at 6 months was 286 micro [p < 0.001]. Intravitreal bevacizumab injection was associated with visual improvement and reduced neurosensory detachment

Brown-Mclean syndrome with keratoconus

We report a case of unilateral Brown-McLean syndrome [peripheral corneal oedema] with bilateral keratoconus. A 30 years old lady presented with decreased vision in her right eye for the last 2 years. There was no history of surgery or trauma. Patient had no systemic illness. There was peripheral concentric corneal oedema extending 2.5-3.5 mm from the limbus involving right eye. On topography, we found bilateral keratoconus. To the best of our knowledge, this combination of Brown-McLean syndrome and keratoconus has not been reported before

Bilateral loss of light reflex and accommodation following 360 peripheral retinal laser therapy

We report a case of bilateral loss of pupillary light reflex and accommodation following 360° peripheral retinal laser therapy. A 24 years old male underwent prophylactic laser barrage for peripheral retinal lattice degenerations. Soon after the procedure, he developed bilateral loss of pupillary light reflex and accommodation. The patient faced difficulty while doing near work. On instillation of 0.125% pilocarpine, both pupils demonstrated the phenomenon of denervation supersensitivity. Damage to the short ciliary nerves was the most likely mechanism responsible for this adverse outcome

Effect of phacoemulsification on intraocular pressure

To evaluate the effect of phacoemulsification on intraocular pressure in normal eyes and glaucomatous eyes. Quasi-experimental study. Layton Rehmatulla Benevolent Trust, Eye and Cancer Hospital, Lahore, from September 2009 to August 2010. The study subjects were adult patients with cataract and open or occludable angle, with or without raised intraocular pressure, who underwent phacoemulsification. Patients having any corneal pathology, synecheal angle closure more than 180 degrees, inflammatory eye disease, previous ocular surgery including YAG iridotomy and endothelial cell density less than 1500/mm[2] were excluded from the study. They were followed-up for one year. Outcome measures included intraocular pressure, angle width, visual acuity and number of antiglaucoma medicines. Results were compared using chi-square test for proportions and t-test for mean values. There were 50 [41%] males and 72 [59%] females with 80 [65.6%] right and 42 [34.4%] left eyes. Mean age was 56.4 +/- 8.57 years. Pre-operatively 52 patients had open angles while 70 patients had occludable angles. Postoperatively 96 patients had open angles and 26 patients had occludable angles. Mean pre-operative IOP was 25.70 +/- 7.79 mmHg, which was decreased to 17.44 +/- 2.8 mmHg [p <0.001] at final follow-up visit. Number of mean antiglaucoma agents decreased from 1.12 +/- 1.30 pre-operatively to 0.62 +/- 0.92 at final follow-up visit. Mean pre-operative visual acuity was 0.4 +/- 0.19 that increased to 0.86 +/- 0.15. Phacoemulsification resulted in reduction in intraocular pressure in normal as well as glaucomatous eyes and it significantly reduced the need for anti-glaucoma medicines
