K. Watanabe et al., ANTERIOR-CHAMBER INFLAMMATION AFTER TRANSCONJUNCTIVAL CRYOSURGERY, Graefe's archive for clinical and experimental ophthalmology, 233(2), 1995, pp. 71-73
Background: Inflammation caused by transconjunctival cryotherapy for p
rophylactic retinal detachment surgery was measured in various conditi
ons. Methods: Thirty-four eyes of 28 patients with peripheral retinal
lesions predisposing to retinal detachment were studied by laser flare
cell meter before and after treatment. Results: The mean flare value
for 34 eyes was 4.06 +/- 1.45 photon counts/ms before surgery and 5.72
+/- 2.52 pc/ms after surgery (p < 0.05). Flare value was elevated at
1, 2, and 3 weeks after treatment, peaking at 2 weeks (p < 0.05), and
normal again at 4 weeks. There were no significant differences in flar
e increase between eyes with and without retinal breaks, eyes with and
without limited retinal detachment, eyes with myopia more and less th
an -8.0 D, and eyes with a treatment area limited to one quadrant and
extending over more than one quadrant. Conclusion: Transconjunctival c
ryosurgery caused mild inflammation in the anterior chamber of the eye
for 3 weeks. The inflammation was not affected by the presence of ret
inal break or limited retinal detachment, the degree of myopia, or the
extent of the treatment area.
