Retinal Tears and Detachment:
The retina is an essential layer of tissue which lines the back of the eye that converts light into an electrical signal which is sent to the brain via the optic nerve. It is often referred to the “film of the eye” and detachment of the retina can lead to permanent blindness if not treated urgently. Retinal tears are the most frequent cause of retinal detachment.
Retinal tears cause sudden flashes of light and a new onset of floaters. If the retinal tear is not treated in short order, the retina detaches a dark curtain starts to block your vison until you no longer can see.
Risk factors for retinal detachment include extreme myopia (nearsightedness), family history of retinal detachment, history of retinal detachment in the fellow eye, eye or head trauma, eye inflammation and lattice degeneration (thinning of the peripheral retina present in 8-10% of people). Retinal detachments may occur at any age but are most common after the age of 40.
This is made by careful dilated in office examination. We use Optos to assist in localizing rears that cause detachments.
If the retinal tear has not yet caused a retinal detachment, they can be treated in the office by using a laser. This is called laser photocoagulation. This procedure creates a seal around the tear preventing fluid from accumulating under the retina and subsequent detachment.
If the tear progress to a retina detachment, then depending on the size and location of the retinal detachment either scleral buckling and/or pars plana vitrectomy are performed. These surgeries are offered by the retina service at InVision.
Scleral buckling involves placing a solid silicone band around the eye wall (sclera) and indenting the wall to close causative retinal breaks. Pars plana vitrectomy is a surgery done through 3 small incisions in the sclera (the white of the eye), whereby the vitreous humor (the gel-like substance that fills the eye between the lens and retina) is accessed and the vitreoretinal traction is released. The retina is reattached, retinal tears are surrounded with laser to induce a scar-like seal, and a vitreous substitute, usually gas, is placed into the vitreous cavity. This gas keeps the retina attached by limiting the flow of fluid under the retinal breaks while the laser scarring forms. The patent will be required to position in a manner that best achieves this in the early postoperative period.
Dr. Gloth is a gifted retinal surgeon who has performed many lasers for tears as well as many types of retinal detachment repairs. We are fortunate to have in our multispecialty practice.
"Kuchunguza video ""Retinal Tears and Detachment"" ni sehemu ya nyuma ya jicho ambayo inabadilisha mwanga kuwa ishara ya umeme ambayo hutumwa kwenye ubongo kupitia neva ya macho." Mara nyingi huitwa "filamu ya jicho" na kutenganishwa kwa retina kunaweza kusababisha upofu wa kudumu ikiwa haitashughulikiwa haraka. Machozi ya retina ndiyo kisababishi cha mara nyingi zaidi cha kutenganishwa kwa retina. Machozi ya retina husababisha mwangaza wa ghafula wa nuru na kuibuka upya kwa viumbe wanaotembea. Ikiwa mlipuko wa retina haujatibiwa kwa muda mfupi, retina huondoa pazia jeusi na kuanza kuzuia maono yako hadi usiweze kuona. Vipengele vya hatari vya retina ya retina ni pamoja na myopia ya hali ya juu, historia ya familia ya retina ya retina, historia ya retina ya retina katika jicho la wenzake, trauma ya jicho au kichwa, uvimbe wa jicho na degeneration ya lattice (kupungua kwa retina ya pembeni inayopatikana katika watu 8-10%). Matatizo ya retina yanaweza kutokea wakati wowote, lakini ni ya kawaida zaidi baada ya umri wa miaka 40. Hii ni kufanywa kwa makini dilated katika uchunguzi wa ofisi. Tunatumia Optos kusaidia katika kugundua nyuma zinazosababisha kujitenga. Ikiwa mlipuko wa retina haujafanya upasuaji wa retina, unaweza kutibiwa katika ofisi kwa kutumia laser. Hii inaitwa photocoagulation ya laser. Utaratibu huu huunda muhuri kuzunguka nyufa hiyo na kuzuia umajimaji wa umajimaji chini ya retina na kuondolewa kwake. Ikiwa mlipuko unaendelea hadi kuondolewa kwa retina, basi kulingana na ukubwa na eneo la kuondolewa kwa retina, ama kuunganishwa kwa scleral na au pars plana vitrectomy hufanywa. Upasuaji huu hutolewa na huduma ya retina katika InVision. Scleral buckling ni kuweka bandhi ya silicone imara kuzunguka ukuta wa jicho (sclera) na indenting ukuta kufunga causative retinal kuvunja. Vitrectomy ya pars plana ni upasuaji unaofanywa kupitia vipande vitatu vidogo katika sclera (nyeupe wa jicho), ambapo vitreous humor (kiungo kinachofanana na gel ambacho hujaza jicho kati ya lensi na retina) hupatikana na traction ya vitreoretin hutolewa. Retina huunganishwa tena, machozi ya retina huzungukwa na laser ili kuunda muhuri unaofanana na kidonda, na mbadala wa vitreous, kwa kawaida gesi, huwekwa ndani ya shimo la vitreous. Gesi hii huhifadhi retina iliyounganishwa kwa kupunguza mtiririko wa umajimaji chini ya mapumziko ya retina wakati maumbo ya laser ya makovu. Upatikanaji wa patent utahitajika kwa njia ambayo inafanya vizuri zaidi hii katika kipindi cha mapema cha baada ya upasuaji. Dr. Glott ni daktari wa upasuaji wa retina ambaye amefanya upasuaji wa machozi na upasuaji wa kuondoa machozi. Tuna bahati ya kuwa na katika mazoezi yetu ya multi-specialty.
