RESUMEN
To observe the difference in IOP that occurs before and after phacoemulsification surgery. A six month study was conducted at Department of Ophthalmology, Unit A, Khyber Teaching Hospital/ Khyber Medical College, Peshawar. Total number of 38 eyes were operated upon. Intraocular pressure was recorded using a Goldmann tonometer. One reading was taken one day before the scheduled operation and the second reading a day after. Universal II model from Alcon[registered sign] Surgical was used in the trial. Types of viscoelastic and IOL were also noted. Based on preoperative [pre-op] and postoperative [post-op] intraocular pressure, they were placed in 2 groups Within the 2 groups, the increase in IOP was statistically significant 24 hours after surgery. Between the groups, the difference was highly significant [P =.003], as determined by Pearson's Correlation test. The increase in IOP was higher in the Viscoat group, 14.28%, as compared to the Hydroxypropyl methylcellulose [HPMC] group, 7.14%. Mean IOP was 14.71 mmHg after surgery as compared to 12.42 mmHg preoperatively. Out of 38 patients 4 [10.5%] had pressures above 20 mmHg. The transient increase in post-op IOP was highly significant 24 hours after surgery in cases where HPMC and Viscoat were used. In cases where Provisc was used no significant elevation of IOP was noted
RESUMEN
Dengue fever is an endemic disease in the tropics and subtropics and has become a health threat worldwide in recent years. Dengue-related ocular complications are increasingly being reported from countries in South-East Asia. The authors report the first documented case of a patient with dengue fever who developed central retinal artery occlusion in addition to many other eye complications such as severe ptosis and complete internal and external ophthalmoplegia during her convalescent phase. The disease was confirmed by specific serological tests. Despite treatment, severe visual impairment occurred in this case.
