To determine the agreement and correlation of visual acuity between Rapid Eye Screening Test (REST) app and Early Treatment Diabetic Retinopathy Study (ETDRS) tumbling 'E' chart. Methods: A visual acuity tool was designed for Android and iOS users based on ETDRS. A pilot study was conducted involving 101 subjects. Visual acuity of each subject was tested using ETDRS chart and crossover to REST at 3 meters or vice versa. Results: Mean visual acuity using ETDRS was 0.086 9 0.194 for right eye (RE) and 0.085 9 0.196 for left eye (LE) while REST measurement was 0.091 9 0.182 for RE and 0.098 9 0.203 for LE. There was significant and strong direct correlation between visual acuity using ETDRS and REST in both eyes (RE: r 0 0.829; p B 0.001, LE: r 0 0.871; p B 0.001). The 95% limits of agreement between the two charts was 90.11 LogMAR for right eye and 90.10 LogMAR for left eye. Time taken for REST was significantly shorter than ETDRS (p B 0.001). Conclusion: REST is accurate and time-saving, thus potentially ideal for mass screening in remote area.

A 7-year-old boy had a case of congenital ptosis of the right eye and has undergone frontalis sling surgery using Gore-tex material. There was no intraoperative or immediate postoperative complication. However, the patient defaulted his follow-up and presented with right eye preseptal abscess secondary to infected surgical wound 1 month after surgery. He was treated with multiple antibiotics and underwent repeated incision and drainage procedures. However, there was still no resolution of the right eye preseptal abscess. The patient’s condition subsequently improved after removal of the Gore-tex material and treatment with an antibiotic combination of ceftazidime and amikacin. Microbiological analysis finally isolated the multidrug resistant Acinetobacter species. At 6 months follow-up, his right upper eyelid was healed with scarring, but without ptosis.

Septic cavernous sinus thrombosis is a rare but often debilitating and potentially fatal disease. We describe a case of bilateral orbital cellulitis with rapidly progressing cavernous sinus thrombosis and left sigmoidal sinus thrombosis in an immunocompetent 20-year-old military man who had undergone intensive physical training. The patient presented with rapid painful swollen left eye for 2 days. The examination results were gross proptosis with total ophthalmoplegia. He was treated with intravenous antibiotics and corticosteroid. At 1 week, visual acuity improved to 20/20 OU, with a normal intraocular pressure. There was a significant improvement in proptosis. The ocular motility of the right eye was fully restored, with slight residual ophthalmoplegia in the left eye. There was no residual illness or recurrence of illness at 3 months' follow-up.
