(4)視網(wǎng)膜脫離的形態(tài):上方的球形脫離裂孔應(yīng)在上方脫離區(qū)內(nèi);下方的球形脫離,上界不清楚,裂孔常在上方;上界呈凸面且與正常視網(wǎng)膜界限分別,或下方的扁平脫離,裂孔常在下方;后極脫離常由黃斑孔引起。
(5)視網(wǎng)膜脫離伴網(wǎng)膜后增殖改變、分界線、視網(wǎng)膜囊腫說明脫離進(jìn)展緩慢,以顳側(cè)及下方的圓孔或鋸齒緣斷離多見,裂孔常位于囊腫附近或在分界線的凹弧范圍內(nèi)。
(6)格子樣變性區(qū)內(nèi)常有圓形裂孔,變性邊緣尤其后極部兩端常發(fā)生馬蹄形裂孔。
(7)玻璃體內(nèi)如有一塊孤立白色混濁物,在其附近視網(wǎng)膜上??砂l(fā)現(xiàn)圓形無蓋裂孔,此混濁物為撕下的裂孔蓋片。
(8)鈍挫傷后的視網(wǎng)膜脫離,當(dāng)見到一灰白或棕色飄帶樣物,懸掛于上方玻璃體中時,常由鼻上方鋸齒緣斷離所致。
(9)經(jīng)反復(fù)檢查均未見到裂孔,但發(fā)現(xiàn)視網(wǎng)膜玻璃體粘連病灶,病史及網(wǎng)膜脫離形態(tài)支持孔源性脫離時,此病灶可當(dāng)作裂孔處理,其中可能隱藏著不易發(fā)現(xiàn)的裂隙。
(10)50%以上病例存在一個以上裂孔。故術(shù)前需反復(fù)檢查,不能滿足于已找到裂孔。另外,應(yīng)避免將視網(wǎng)膜出血及色素斑視作裂孔處理。
如何選擇孔源性視網(wǎng)膜脫離手術(shù)方法?
孔源性視網(wǎng)膜脫離手術(shù)的選擇,應(yīng)根據(jù)視網(wǎng)膜脫離的性質(zhì),脫離的范圍,裂孔的大小、形態(tài),變性區(qū)域,視網(wǎng)膜表面膜形成,玻璃體程度,是否再手術(shù),采用冷凝還是電凝封洞等因素而決定。手術(shù)目的是封閉裂孔,消除或減輕玻璃體對視網(wǎng)膜的牽引,去除增殖膜使視網(wǎng)膜游離。
鞏膜層間縮短術(shù):能縮短眼球前后徑,條圓帶推頂裂孔使脫離網(wǎng)膜與脈絡(luò)膜緊貼。適合網(wǎng)膜周邊部無牽引的圓形小孔。
鞏膜外墊壓、不放液術(shù):利用外墊壓物形成的嵴,使脫離的網(wǎng)膜與脈絡(luò)膜相貼。適用于新鮮扁平的赤道前后的馬蹄形裂孔,或較大的圓形、橢圓形裂孔。
(4) retinal detachment morphology: the top of the spherical detachment from the hole should be above the area; the bottom of the spherical detachment, the upper boundary is not clear, the hole often above; the upper boundary was convex and the normal retina, respectively, or below the flat Detachment, often at the bottom of the hiatus; posterior detachment often caused by the macular hole.
(5) retinal detachment with retinal proliferation changes, demarcation line, retinal cysts shows detachment progress slow to the temporal and below the round hole or serrated edge off more common, often located in cysts near the cyst or concave line in the arc Range.
(6) Lattice-like degeneration often have circular holes, and degeneration edges, especially horseshoe-shaped holes, often occur at both ends of the posterior pole.
(7) If there is an isolated white opacity in the vitreous body, a round, uncovered hole may often be found in the retina near it. The opacity is a tear-off hole cover.
(8) retinal detachment after blunt contusion, when you see a gray or brown streamers, suspended in the upper vitreous, often caused by the serrated edge of the nose off.
(9) Holes were not seen after repeated examinations. However, when the retinal vitreous adhesions, history of disease and retinal detachment were found to support osteoclastic detachment, the lesion could be treated as a fissure hole, which may hide hard-to-find fissures.
(10) More than 50% of cases have more than one hole. Therefore, the need to repeatedly check the preoperative, can not be satisfied to find a hole. In addition, retinal hemorrhage and pigmentation should be avoided as a hole treatment.
How to choose rhegmatogenous retinal detachment surgery?
The selection of rhegmatogenous retinal detachment surgery should be based on the nature of retinal detachment, the scope of detachment, the size of the hole, the shape of the degeneration region, the formation of retinal surface membrane, the degree of vitreous atrophy, whether to re-surgery, the use of condensation or electrocoagulation Factors to decide. The purpose of surgery is to close the hole, eliminate or reduce the traction of the vitreous on the retina, remove the proliferative membrane so that the retina free.
Scleral shrunk between the layers: to shorten the eye before and after the diameter, with a round hole to push the top hole off the omentum and the choroid close. Suitable for the peripheral retinal traction without round holes.
Scleral pad pressure, do not release fluid surgery: the use of pressure pad formation of the ridge, so that the detachment of the omentum and choroid paste. For horseshoe-shaped holes before and after fresh and flat equator, or larger round, oval holes.
