Abstract

PURPOSE
To determine the correlations of intraocular pressure (IOP) with risk factors in rhegmatogenous retinal detachment (RRD) patients.
METHODS
A total of 113 eyes in 113 consecutive patients with RRD were enrolled in this study. IOP was measured using applanation tonometry at the initial visit. Based on the difference in IOP between the affected and unaffected eyes, the subjects were divided into two groups: group 1 (IOP difference ≤ 2 mmHg) and group 2 (IOP difference > 2 mmHg). Correlations between the IOP and RRD morphology, visual acuity (VA), best-corrected VA (BCVA), retinal break size and location, range of retinal detachment, macular involvement, and proliferative vitreoretinopathy were analyzed.
RESULTS
The IOP at the initial visit was 12.88 ± 3.2 mmHg in the affected eyes and 14.27 ± 2.5 mmHg in the unaffected eyes. The IOP difference between the affected and unaffected eyes was −1.40 ± 2.82 mmHg. The BCVA and range of retinal detachment showed statistically significant differences between groups 1 and 2.
CONCLUSIONS
In patients with RRD, the IOP difference compared to the unaffected eye was correlated with the extent of area of retinal detachment and decreased BCVA.

Figure

  • Figure 1 Detachment chart. Outer circle represents ora serrata and inner circle represents equator of the globe. Each 12 perpendicular black line indicates 30 degrees. Using the blue lines which indicates 45 degrees, we describe the extent of detachment in 8 regions (superior, superotemporal, temporal, inferotemporal, inferior, inferonasal, nasal, superonasal).

  • Figure 2 Distribution of the largest retinal tear position. Group 1, the total of 52 eyes were involved. Group 2, the total of 61 eyes were involved. The difference of distribution between the two groups was not statistically significant (p = 0.626, chi square test).
