METHOD
A method of using a vector comprising a transgene to treat a disease or condition of the eye, the method comprising the steps: (a) administering a solution to a mammalian subject by subretinal injection in an amount effective to at least partially detach the retina to form a subretinal bleb, wherein the solution does not comprise the vector; and (b) administering a medicament composition by subretinal injection into the bleb formed by step (a), wherein the medicament comprises the vector and is injected in an amount effective to treat the disease or condition; wherein the transgene is expressible in cells of the mammalian subject.

4 . The method of claim 1 , wherein the transgene comprises a Rab escort protein-1 (REP1) or retinal pigment epithelium-specific 65 kDa protein (RPE65) open reading frame operably linked to an expression control sequence to promote expression in cells of the eye of the mammalian subject.
5 . The method of claim 1 , wherein the vector is delivered to cells of the neurosensory retina, retinal pigment epithelium and/or choroid.
6 . The method of claim 1 , wherein the medicament composition is administered by subretinal injection through the same retinotomy used to administer the solution.
7 . The method of claim 1 , wherein the subretinal injections are carried out using a subretinal injection needle to create self-sealing entry points in the neurosensory retina.
8 . The method of claim 1 , wherein the area of the retina to be injected is dyed with a blue vital dye before the subretinal injection of step (a) is carried out.
9 . The method of claim 1 , wherein the subretinal injections are at positions greater than or equal to about 1 mm from the fovea.
10 . The method of claim 1 , wherein the subretinal injections of steps (a) and/or (b) are made in a series of successive pulses to stretch and blanch the retina.
11 . The method of claim 1 , wherein the solution injected in step (a) is balanced salt solution (BSS).
12 . The method of claim 1 , wherein the disease or condition is a retinal dystrophy.
13 . The method of claim 1 , wherein the disease or condition is choroideremia, Leber congenital amaurosis, cone-rod dystrophy, macular dystrophy, cone dystrophy, achromatopsia, retinitis pigmentosa or age-related macular degeneration.
14 . A method of treatment of a disease or condition of the eye, the method comprising administering a vector comprising a transgene by the steps:
(a) administering a solution to a mammalian subject by subretinal injection in an amount effective to at least partially detach the retina to form a subretinal bleb, wherein the solution does not comprise the vector; and
(b) administering a medicament composition by subretinal injection into the bleb formed by step (a), wherein the medicament comprises the vector and is injected in an amount effective to treat the disease or condition;
wherein the transgene is expressible in cells of the mammalian subject.
15 . The method of claim 14 , wherein the vector is a viral vector.
16 . The method of claim 15 , wherein the viral vector is an AAV, retroviral, lentiviral or adenoviral vector.
17 . The method of claim 14 , wherein the transgene comprises a Rab escort protein-1 (REP1) or retinal pigment epithelium-specific 65 kDa protein (RPE65) open reading frame operably linked to an expression control sequence to promote expression in cells of the eye of the mammalian subject.
18 . The method of claim 14 , wherein the vector is delivered to cells of the neurosensory retina, retinal pigment epithelium and/or choroid.
19 . The method of claim 14 , wherein the medicament composition is administered by subretinal injection through the same retinotomy used to administer the solution.
20 . The method of claim 14 , wherein the subretinal injections are carried out using a subretinal injection needle to create self-sealing entry points in the neurosensory retina.
21 . The method of claim 14 , wherein the area of the retina to be injected is dyed with a blue vital dye before the subretinal injection of step (a) is carried out.
22 . The method of claim 14 , wherein the subretinal injections are at positions greater than or equal to about 1 mm from the fovea.
23 . The method of claim 14 , wherein the subretinal injections of steps (a) and/or (b) are made in a series of successive pulses to stretch and blanch the retina.
24 . The method of claim 14 , wherein the solution injected in step (a) is balanced salt solution (BSS).
25 . The method of claim 14 , wherein the disease or condition is a retinal dystrophy.
26 . The method of claim 14 , wherein the disease or condition is choroideremia, Leber congenital amaurosis, cone-rod dystrophy, macular dystrophy, cone dystrophy, achromatopsia, retinitis pigmentosa or age-related macular degeneration.
27 . A kit comprising: (i) the vector as defined in claim 1 ; and (ii) a solution that does not comprise the vector for use in at least partially detaching the retina of a mammalian subject to form a subretinal bleb.
28 . The method of claim 1 , wherein the vector is an AAV vector and the transgene comprises a Rab escort protein-1 (REP1) open reading frame operably linked to an expression control sequence to promote expression in cells of the eye of the mammalian subject.
