Case ReportsValsalva retinopathy-like hemorrhage associated with combined trabeculotomy-trabeculectomy in a patient with developmental glaucoma.
This case describes valsalva retinopathy-like hemorrhage in a patient with developmental glaucoma who underwent primary combined trabeculotomy-trabeculectomy. A 12-year-old boy with developmental glaucoma in both eyes developed shallow anterior chamber following combined trabeculotomy-trabeculectomy in his right eye. ⋯ The patient was treated with betamethasone and cyclopentolate in the postoperative period, and was followed by complete absorption of the retinal hemorrhages with retention of normal visual acuity. Valsalva retinopathy-like hemorrhage may occur with valsalva maneuver during general anesthesia.

To report a unique case of intramuscular lipoma of the eyelid and to alert surgeons to this entity that simulates a common dermoid cyst. A slowly-growing mass of the upper eyelid was excised from a 62-year-old man. ⋯ Lipomas, including the intramuscular variety, are common tumors elsewhere in the body. The differential diagnosis of eyelid masses should include this entity.

Case ReportsTraumatic subconjunctival dislocation of the crystalline lens and its surgical management.
The authors report a case of a 40-year-old female who had sustained a blunt ocular trauma resulting in anterior scleral rupture and subconjunctival dislocation of the crystalline lens. Anterior segment ultrasound aided in the diagnosis. Surgical exploration revealed a 6 mm long anterior scleral rupture which was repaired. Postoperatively the patient had a best corrected visual acuity of 6/18.

Comparative StudyCombined lensectomy, vitrectomy and scleral fixation of intraocular lens implant after closed-globe injury.
To describe our experience in the surgical management of cataracts in patients with complications of closed-globe injury using pars plana lensectomy (PPL), pars plana vitrectomy (PPV), and scleral fixation of posterior chamber intraocular lens (PCIOL). ⋯ In patients undergoing PPL, PPV and scleral fixation of PCIOL for cataract after a closed-globe injury, a substantial visual improvement occurred in a majority of the involved eyes.

Randomized Controlled Trial Comparative Study Clinical TrialApraclonidine 0.5% versus brimonidine 0.2% for the control of intraocular pressure elevation following anterior segment laser procedures.
Both apraclonidine hydrochloride 0.5% and brimonidine tartrate 0.5% are potent alpha-2 agonists, effective in controlling the intraocular pressure (IOP) rise following argon laser trabeculoplasty (ALT). Brimonidine has recently become available commercially as a 0.2% solution. Our goal in this study was to compare the efficacy and side effect profile of 0.2% brimonidine to that of 0.5% apraclonidine in the prevention of IOP spikes following anterior segment laser procedures. ⋯ Both drugs are highly effective in controlling IOP spikes following anterior segment laser procedures. There is a tendency toward higher risk of IOP rise following argon laser trabeculoplasty with 0.2% brimonidine as compared to 0.5% apraclonidine, however, this was not statistically significant.
